Try to create several gigs at once, and then experiment and see which one is more popular. Remove ones that have no or few views/impressions, and create new ones - keep optimising but no need to overdo it. Avoid sitting around and just waiting to receive an order - go out there and spread the word out. Facebook group for Fiverr promotion is a good place to start and for free. Best of luck

P.S. most of all - be patient and your 1st order will eventually arrive!
